[0008] Further, the guide mechanism includes two guide shafts and a reinforcing rib connected between the two guide shafts.
[0009] Further, the test frame is provided with shaft hole on four corners, and the guide shaft passes through the shaft hole.
[0010] Further, the base is provided with heat dissipation plate around.
[0011] Compared with the prior art, the utility model has the beneficial effects that:
[0012] 1. After the brick is placed on the base, the jig is pressed, the test probe is inserted into the module lead, the jig pressure buckle is fixed for the test frame power supply, the toggle switch is turned on, and various function tests are carried out. The application can better improve the function test efficiency of DC / DC power module control board, the efficiency is improved several times compared with manual operation, and the demand of large-scale production can be met.
[0013] 2. This tool test also meets the power of the brick, the bottom of the heat sink can ensure the heat dissipation effect, prevent the test when the over temperature protection.
[0014] 3. The tool structure is simple, convenient to operate, the positioning module and the test plate can be quickly replaced, so that the functional test requirements of different specifications and models of DC / DC power supply modules are met, and the tool has good universality and expansibility.
[0015] The professional skill requirement of the operator is reduced, the test error caused by manual operation failure is reduced, and the product quality is improved. BRIEF DESCRIPTION OF DRAWINGS
